Researchers from the University of Zurich’s Robotics and Perception Group have proven that this does not need to be the case by keeping a quadcopter flying with only three motors. A quadcopter ...

According to the team’s results, the BrainGate array wired directly to motor neurons offered a “sixfold improvement” on the ...

For more projects involving motors, read up on this brushless motor made from 3D-printed parts and this guide to hand-winding quadcopter motors.

The authors believe that to restore highly functional fine motor control, electrodes need to be placed closer to the neurons. The study notes a sixfold improvement in the user's quadcopter flight ...
